Heliopan ND Filter (Bay 70, 3-Stop)
Key Features
  • 0.9 Optical Density
  • Front and Rear Coating
  • Schott Glass Construction
  • Brass Filter Ring
This 3-stop, Bay 70 Heliopan ND Filter is a solid ND filter. This 0.9 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject.

Heliopan Neutral Density Filter Overview

This 3-stop, Bay 70 Heliopan ND Filter is a solid ND filter. This 0.9 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

ND 0.9 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
